20 Claims,

This invention relates to winding machines for winding yarn, thread andsimilar textile materials into packages, such as cops, bobbins, pirnsand the like. More specifically, the invention relates to the'carmarking or identifying of textile packages as they are produced onthe winding machine.

In the present specification and claims the term yarn is employed toindicate all kinds of attenuated material and the term bobbin is used todesignate the wound package whatever its form or character.-

It is a common practice in textile mills to identify filling yarn bymarking the bobbins with crayon or chalk to indicate different types andcounts of the yarn and also to identify the machine or department inwhich the yarn is processed or handled. The operator of the machinemarks the yarn on the bobbin by drawing a piece of chalk or crayonacross the surface of the wound bobbin, but this operation has certaindisadvantages a it is liable to cause the chalk dust to infiltrate intothe mechanism of the machine to interfere with its proper functioning.Moreover, it is impractical to apply chalk or crayon marks to certaintypes of filling such as worsted r woolen yarn.

The practice of marking bobbin for identification of the yarn is for thepurpose of preventing mixed counts or difierent twists of filling fromgoing to the same loom and becoming incorporated in the fabric. In suchcase the difference in the size or twist of the filling does not becomeevident until the cloth is woven and therefore often results in spoilageor seconds in the product of th mill. When the bobbins are properlymarked the weaver can discover if mixed yarn is furnished to the weaveroom and place the responsibility in the winding room or otherdepartment of the mill where the yarn is processed or handled. In otherinstances, by applying several distinguishing marks to the yarn on thebobbin its progress from the source can be followed and when poor orimperfect bobbins reach the weave room they can be traced to the machinein which they were wound or to the department in which the yarn wasprocessed. In some mills different types or counts of yarn are wound ondifferent spindles of the same machine and the bobbins may become mixedthrough carelessness of the operator, as by the dropping of bobbins onthe floor or by incomplete emptying of the collecting boxes for one typeof yarn before bobbins of another type are placed therein. Most millshandle more than one count of yarn at the same time and as the countsmust be kept separate it i an object of the present invention to provideautomatically-operated apparatus for earmarking or identifying thebobbins as they are produced in the winding machine by attaching anidentification tag or ticket thereto to prevent mixed counts from beingwovenvln the loom; and further, to trace the steps in the processing ofthe yarn in different departments of the mill to correct defects ordeficiencies in its manufacture.

Another object of the present invention is to provide an apparatus ofthe type indicated which is adapted to be applied to existing windingmachines as an attachment.

Another object is to provide an apparatus 0 the type indicated which isadapted to feed a tag or ticket from a continuous strip thereof intoposition to be gripped between the winding yarn strand and bobbin and tosever the ticket from the remainder of the strip.

Another object is to provide an apparatus of the type indicated which isautomatically-operated to apply the ticket in proper timed relation tothe winding operation.

Still another object is to provide an apparatus of the type indicatedwhich is reliable in operation to feed and sever the tickets and ofsimple and compact construction to adapt it for economical manufacture.

Further objects of the invention are set forth in the followingspecification which describes a a preferred form of the apparatus, byway of example, as illustrated by the accompanying drawings. In thedrawings:

While the present invention may be applied to use with eithermanually-operated or automatic winding machines, it is herein describedand illustrated in connection with an automatic bobbin winder of thetype disclosed in the copending applications for United States LettersPatent,

Serial No. 231,044, filed September 21, 1938, by

C. D. Reynolds et al., now Patent No. 2,257,651 issued Sept. 30, 1941,and Serial No. 385,346, filed March 26, 1941, by C. D. Reynolds et ai.,now Patent No. 2,302,715 issued Nov. 24, 1942. The machines illustratedin these prior applications: for patent are completely automatic intheir operation to provide for donning empty cores or yam carriers,winding the yarn thereon, and domng the bobbins as they are completed.It is therefore desirable that a machine of this type shall be furtheradapted for earmarking or applying indicia to the bobbins automaticallyto identify them after theyhave been delivered from the machine. On theother hand, it is to be understood that the present invention is notlimited to use with automatic winding machines, but may be applied toother types of winders for labeling the bobbins before they are doffed.

Referring to the drawings, in Fig. 1 a portion of a winding machine isillustrated comprising a frame or casing 2, and projecting from bearingstherein is a rotary winding spindle 3. The wind ing spindle 3 carries acup-shaped member 4 at its outer end for receiving the head h of awooden core or bobbin D such' as used in either plain or automaticfilling-changing looms. The opposite or tip end of'the bobbin b. is heldin a similarv recessed member 5 on a spindle 6 mounted free to rotate ina bearing sleeve 1 supported by an upright bracket 8 attached to the endof a horizontal arm 9 projecting forwardly from the side of the machineframe 2, see Fig. 2. In the type of machine illustrated herein the yarn1/ is wound on the core or wooden bobbin b by means of a thread-guideII] which has a relative traversing motion axially of the bobbin and isadvanced progressively longitudinally thereof to deposit the yarn incourses of cross-wound coils which overlap at their forward ends.Consequently, the bobbin B grows by longitudinal extension, being formedwith a conical base, a cylindricalbody portion and a tapered or conicaltip end as indicated by dot-and-dash lines in Fig. 2.

The thread-guide I is carried on a reciprocabletraverse-rod l mounted toslide longitudinally in a bearing in the frame or casing 2 with itsouter end supported by an outboard bearing l8 carried on the bracket 8,referred to previously as the support for the spindle bearing-sleeve I.The traverse-rod I5 is reciprocated longitudinally in its bearings by asuitable cam or similar means enclosed within the frame or casing 2 ofthe machine, but not herein illustrated as such traversing mechanism iswell known to those versed in the art. The yarn y delivers from itssource of supply, usually supported above the machine, but not hereinshown, and feeds to the bobbin through an eyelet l1 in-the thread-guideHI. Connected to the thread-guide ill is a ro-- tatable contact-disk ortraverse-wheel 20 mounted on a sleeve-like nutv 2| which is iriteriorlythreaded to engage the screw-threads 22 on the traverse-rod is. It willbe understood that the thread-guide HI is positioned adjacent therearward or butt end of the yam-carrier or wooden bobbin b at the startof the winding and the traverse-wheel 20 is so related thereto that eachtime the guide makes a return stroke to the left, as viewed in Figs. 1and 2, the periphery of the wheel will contact the yarn wound on thebobbin to turn the nut 2| through a part of a rotation to feed the guideforward to a slight extent along the traverse-rod. This method ofadvancing the layers of winding along the bobbin by the intermittentadvance of the thread-guide is illustrated and described in the priorapplications referred to above and well known to those versed in theart.

At the completion of the bobbin the threadguide [0 will be positioned atthe forward or tip end of the bobbin when at the furthermost limit ofits forward stroke and at this point the guide, or a part connectedtherewith, engages a stop or abutment to move the latter to causeactuation of the stopping mechanism of the machine, this mechanism beingemployed generally in machines which require manual dofiing and donning.In automatic machines such as described in the pending applicationsreferred to above, the completion of the bobbin efiects initiation ofthe operation of means for dofilng the wound bobbin, donning an emptycore or yarn-carrier, attaching the end of the yarn to the emptycarrier, severing the yarn from the doifed bobbin, returning thethread-guide to initial winding position, and again starting the windingoperation. The automatically-operated mechanism for performing thesefunctions is described in the prior patent applications hereinbeforementioned and is not referred to specifically herein as it forms no partof the present invention. Suifice it to state'that as the wound bobbin Bis dofied by releasing it from the .driven winding spindle 3, it dropsby gravity into a chute 23 arranged therebelow.

It is the common practice in winding filling bobbins to wind a fewclosely adjacent coils on the butt end of the core or carrier 12 at thebeginning of the winding operation to form a bunch X which provides areserve length of yarn in the shuttle to prevent misspicks when thefilling is changed. The winding of such a bunch may be controlled by aseparate thread-guide, commonly known as a bunch-builder, or theoperation of the thread-guide may be restricted to wind with a shortstroke at the beginning of the winding to cause the bunch to be wound,such devices being well known to those versed in the art.

In accordance with the present invention an identification tag or ticketT is attached to the bobbin by inserting it under the yarn strand ywinding on the carrier b at the beginning of a winding operation tocause it to be gripped to the bobbin by the bunch windings. The ticket Tas illustrated in the present drawings may consist in a length of paperstrip detached from a continuous supply t and printed or marked toiden-- tify the particular yarn and/or winding unit on which it iswound. For example, the ticket T may have a particular color forindicating the count or size of the yarn with identifying indiciaprinted thereon, such as the characters A-8 illustrated in Fig. 2 of thedrawings, for indicating the source of supply or the particular spindleon which the yarn is wound; or the reference character A may denote themachine on which the bobbin was wound and the numeral 3 indicate theparticular spindle of that machine unit. It may be desirable in someinstances to further identify the characteristics of the particularbobbin, such as the twist of the yarn or the particular lot in which theyarn was dyed and anyother characteristic which may be indicated byadditional reference characters such as A-8I.

As illustrated in Figs. 1 and 2 the ticket-strip t is coiled to form aroll 25 which is mounted to rotate on a support or bracket 26 attachedto the casing 2 of the winding machine. The supporting bracket 26, shownin Fig. 1,-ls of bifurcated form having spaced arms for receiving theroll 25 of paper strip t therebetween and having a spindie 21 extendingbetween the arms and through the center of the roll to adapt the latterto rotate thereon. To apply the roll 25 for feedin the ticket-strip t itis only necessary to insert the spindle 2'! through the arms of thesupporting bracket and center of the roll. Ad'iacent the bottom of thebracket 26 is an elbow-shaped arm 28, see Figs. 1 and 2, under which thestrip if is inserted to guide it off from the roll 25.

Mounted on the machine frame or casing 2 adjacent the bracket 26 is aticket-supplying mechanism 30 adapted to feed the ticket-strip t adistance equal to the length of a ticket T to be an plied and arrangedto sever the ticket from the remainder of the strip. The ticket-applyingmechanism 30 comprises a channel-shaped base,

3|, see Fig. 7. having a bottom wall 34. side walls 32 and 33 extendingu wardly from the bottom wall and a rearward end wall 35. Preferably,the base 3! is made from a single piece of sheetmetal folded intochannel-shape with the inner side wall 32 and end wall 35 considerablyhigher than the side wall 33. The base 3| is mounted on the machine bymeans of a bracket 36, see Figs. 1, 2 and 5, bolted to the end wall 35and having an angular portion clamped between the bracket 26 and a ledgeon the machine frame 2.

The bracket 36 as herein shown is so constructed and arranged as toposition the open end of the channel-shaped base 3| at an acute an le tothe axis of the bobbin b' adiacent the butt. end of the latter, see Fig.2, and slightly inclined downwardly toward the axis of the bobbin. seeFig. 1. It is to be understood. however. that the base 3| may be mountedin any suitable relation to feed a ticket T into position to be bound tothe bobbin by the coils of yarn wound thereon. For example, the base 3|may be placed parallel to the axis of the bobbin to provide for applyingthe ticket T in line with the barrel of the bobbin b as illustrated inFig. 9.

A pair of curved springs 3'! and 38 are provided at the rearward end ofthe base 3! extendin downwardly and forwardly, see Fig. 5. to adapt theticket-strip t to feed therebetween. The spring 31 is attached to theupper portion of the end wall of the base 3| and extends downwardly andforwardly therefrom to overlie the bottom wall 34 thereof. The spring 38has its upper end attached to an angular bracket 39 fastened to the sidewall 32 of the base 3| and extends downwardly and forwardly therefromwith its free end converging toward the free end of the spring 31. Thus,the pair of springs 31 and 38 provide a guide for the ticket-strip t andalso act to tension the strip when the latter is fed therethrough tohold it against rearward movement. A leaf-spring 40 is attached at oneend to the outsideface of the side wall 33 of the base 3! and shapedwith an offset curved portion 4| at its opposite end forming a detentwhich slide 43 having a bottom wall- 44 and spaced side walls 45 of suchdimensions as to adapt the slide to fit closely within the sides of thechannelshaped base 3!. As illustrated most clearly in Fig. 7, theforward portions of the side Walls 15 of the slide 43 are of reducedheight to provide vertical shoulders 46 intermediate the ends of theslide. ward side 32 of the base 3i with its bottom edge overlying theupper edge of one of the side Walls 45 of the slide 43 to restrain thelatter from rising in the base while guiding its longitudinal slidingmovement therein. The slide 53 is limited in its rearward movement bythe engagement of its rearward end with the end wall 35 of the base 3iand its forward movement is limited by the engagement of the shoulders86 intermediate its ends with lugs 48 extending inwardly to- A guide-bar4'! is attached to the rear-- ward each other from the forward edges ofthe side walls 32 and 33 of the base.

Referring to Fig. ,7. the outer side wall 35 of the slide 43 has avertical groove 69 adjacent its rearward end which is adapted to beengaged by the detent 4i projecting inwardly through the opening 42 inthe side wall 30 of the base 31 and the bottom wall 4d of the slide hasa sharpened cutting edge 5| on the forward side of a transverse slot oropening 50 therein. Welded or otherwise attached to the bottom wall d4of the slide 43 at its rearward end is a leaf-spring 52 having itsforward end curved upwardly slightly above the opening 50. The spring 52is of relatively thin stock to adapt its upwardly curved end to yield tobe depressed into the opening 53 in the bottom wall 44 of the slide 63.Projecting inwardly from one of the side walls 415 of the slide 43 is alug 53 which functions for a purpose as explained hereinafter. As willbe noted by ref erence to Fig. 7, the forward corner of the slide 43 iscut away and gradually rounded with the Side wall 45 terminating shortof the end of the slide to permit free delivery of a ticket T therefromas the bobbin B rotates with the ticket bound thereto.

Mounted to rock on the slide 43 is a gripping member 55, see Figs. 5 and6. inthe form of a mally overlies the upwardly bent end of the spring52, being curved downward y with its forward edge constituted as a knifeor cutter for cooperating with the cutting edge 5| at the side of theopening 50 in the bottom of the slide 43 to function as shears. Aresilient finger 6! is attached to the upper face of the horizontal arm56 of the gripping member 55.by means of a screw 62 with its forward endcurved downwardly toward the bottom wall of the slide 43 forwardly ofthe opening 50 to overlie a slight recess 63 formed therein.

The vertically-extending arm 51 of the gripping member 55 is curvedrearwaldly at its upper end and projecting forwardly from its side is afinger 65 which may be formed integral therewith or attached to itsforward face by an extension 64 welded or brazed thereto as shown inFig. 7. The'finger 65 overlies the upper edge of the wall 33 of the base3| to adapt it to engage therewith to limit the rocking movement of thegripping member 55 on the slide 43 in counterclockwise direction asviewed in Fig.- 5 during the major portion of the forward stroke of theslide. As will be noted by reference. to Fig. 7, the forward end oftheside wall 33 of the base 3| is beveled off or inclined downwardly, asindicated by the reference character 66, to permit an added rockingmovement of the gripping member 55 in counterclockwise direction at theend of the forward stroke of the slide 43. The rocking movement of thegripping member 55 on the slide 43 in ciockwise direction, as viewed inFig. 5, is limited by the engagement of the resilient finger 6| with thelug 53 projecting inwardly from the side wall 45 of the slide.

The gripping member 55 is rocked on the pivotpin 58 and the slide 43reciprocated with respect to the base 3| by the energization of anelectromagnet having a U-shaped magnetic frame 10 attached to the sidewall 33 of the base; Mounted on one arm 1| of the frame 10 is anelectromagnet winding in the form of acoil 12, the wall 33 f the bracket3| being recessed to provide an opening for the bottom portion of thecoil. The

V opposite arm 13 of the frame 10 has a bifurcated end for receiving thereduced end 14 of an armature 15. The armature 15 is pivotally mountedon the arm 13 of the frame 10 by means of a pin 16 extending through thebifurcations and the reduced end 14 of the armature. The lower free endof the armature 15 extends forwardly in the form of a plunger 11, seeFig.- 7, the bottom face of which is of arcuate shape to adapt it tocooperate with the corresponding arcuate upper face of the arm 1| of theframe 10. The armature I is adapted to be rocked in c0unterclockwisedirection away from the arm 1| of the frame by means of a hairpin-shapedspring 18, see Fig. 5, coiled about its pivot-pin 16 with one endengaging the'arm 13 of the frame 10 and its opposite end engaging thearmature 15. Upon energization of the magnet the plunger '11 is drawninto the coil 12 by magnetic attraction causing the armature I5 to rockon its pivot-pin 16 in clockwise direction as viewed in Figs. 5 and 6.

A sheet-metal member 83 mounted on the side of the armature 16 by meansof screws 82 has a laterally offset intermediate portion 84 extended ina forwardly-projecting arm 85 which terminates in a downwardly inclinedfinger 86. Pivotally mounted on a pin 92 projecting from 9| coiled aboutthe pivot-pin 92 with one endbearing against the finger 90 and itsopposite end bearing against the arm 85. The member 83 is so constructedand arranged as to position the fingers 86 and 90 on opposite sides ofthe upright arm 51 of the gripping member 55 when the slide 43 is in itsrearmost position.

Upon energization of the magnet coil 12 to rock the armature on itspivot 16 the finger 90 on the bracket 83 engages the rearward side ofthe upright arm 51 of the gripping member 55 to thereby rock the latterin counterclockwise direction to cause the resilient finger 6| to gripthe ticket-strip t against the bottom wall of the slide 43. Sincerocking movement of the gripping member 55 is limited by the engagevment of its longitudinally-extending finger 65 the arm 85 of the member83 is an auxiliary member will engage the forward face of the uprightarm 51 of the gripping -member 55 to rock it in clockwise direction torelease the ticket-strip t and return the slide 43 to initial position.

The energization of the magnet coil 12 may be controlled in any suitablemanner, but pref erably it is under the control of a controller of thetyne illustrated and described in the Reynolds et al. applicationsreferred to above. Suflice it to state herein that the controllercomprises a cam-shaft 96, see Fig. 8, having a cam 91 thereon foroperating a switch 98 in an electric circuit including the magnet coil12. Thus, at a particular time during the rotation of the shaft 96 thecam 91 closes the switch 98 to energize the magnet coil 12. Thecontroller cam-shaft 96 is adapted to rotate through one completerevolution and has a series of cams as indicated in Fig. 8 forcontrolling branch circuits in timed sequence to arrest the windingoperation upon completion of a bobbin, doff the wound bobbin B, don anempty bobbin 1), start the winding of a new bobbin, and attach a ticketthereto. Fig. 8, illustrates parallel branch circuits adapted to controlthe donning of an empty bobbin b and the starting of a new windingoperation. The circuit for controlling the don- .ning of an empty bobbinb comprises a cam I00 on the control shaft 96. a switch |0| and a magnetwinding I02, while the circuit for starting a new winding operationcomprises a cam I03 on the control shaft 96, a switch |04 and a magnetwinding I05. It will be understood that the cams I00, 91 and I03 are soarranged as to actuate the switches MI, 98 and I04 in timed sequencewhereby an empty bobbin b is donned, a ticket T fed between the yarnstrand y and the bobbin b and a new winding operation started to causethe ticket to be gripped between the coils of the winding strand and thebobbin. One form of the invention having been described in detail themode of operation of the device is explained as follows:

A roll 25 of .the ticket-strip t having the proper color and identifyingindicia printed thereon is mounted on the bracket 26 between itsbifurcated arms and the pin 21 inserted through the arms and center ofthe roll. It will be understood that-a similar roll 25 having the properidentifying indicia is sufiplled to each unit of forwardly from theslide as illustrated in Fig. 2.

Considering that the machine is operating, upon completion of thewinding of a bobbin B the thread-guide ID will be at the outer end ofthe traverse-rod I5 and as the latter makes a forward stroke the guide,or a part attached thereto, will strike an abutment or other means tomove the latter to set into operation the doifing and donning mechanismsof the machine. The various mechanisms for this purpose are under thecontrol of electromagnets adapted to be energized by circuits which areclosed by the several cams on the controller-shaft 95, indicated in thediagrammatic view, Fig. 8. The controller-shaft 95 is connected torotate through a clutch or other. means shown and described in theReynolds et al. applications referred" to previously herein. As thefirst step in the dofiing and donning operation the spindle-cup 4 isretracted to release the wound bobbin B which drops by gravity into thechute 23. An empty bobbin or yarn-carrier b is then transferred intoposition betweenthe spindle-cup 4 and the recessed member 5 on theopposed spindle 6 with the strand of yarn y trailing from the woundbobbin B and positioned between the spindlecup and the butt end of theempty bobbin. The cam I on the controller-shaft 96 then acts to releasethe switch |0| to open the circuit to h the electromagnet winding It torelease the spindle-cup 4 whereby it is projected forwardly by means ofa spring. not herein shown, to grip the empty bobbin between the cup andthe recessed member on the spindle 5; the yarn strand y being therebyclamped against the end of the bobbin. The winding spindle 3 is thenstarted to rotate through the means of suitable clutch-devices, notherein shown, whose action is initiated by electromagnetic means, asdescribed in detail in the pending application Serial No. 385,346referred to above. As the winding spindle 3 is driven to rotate thebobbin b the trailing end of the yarn leading to the doffed bobbin issevered automatically and at this juncture the bunch-building meanscomes into action to restrict the traverse of the yarn as thethreadguide II) is reciprocated by the traverse-rod I5 coincidentallywith the rotation of the winding spindle.

spindles 3 and 6 the cam 91 on the controllershaft 95 functions to closethe switch 93 to complete the circuit to the electromagnet winding 12 ofthe actuator for the ticket-applying means 30. Energization of theelectromagnet winding .12 causes the armature 75 to be attracted androcked in clockwise direction, as viewed in Fig. 5, to actuate thestrip-feeding means to advance the strip t a distance equal to thelengthof a ticket T. This rocking movement of the armature '35 causes thefinger 90 at the end of the arm 81 to engage'the upright arm 51 of thegripping member 55 to rock the latter on its pivot-pin 58 and therebypress the forward end of its arm 56 against the ticketstrip 't to gripit against the end of the spring 52 on the bottom wall 44 of the slide43. During this action the slide 43 is restrained momentarily fromlongitudinal sliding movement along the base 3| by the engagement of thedetent 4| at the end of the yieldable spring 40 with the groove 49 inthe side of the slide, see Fig. '7. The restraint of the movement of theslide 43 will cause the finger 90 to rock slightly against the tensionof its spring 9|, this yieldable action of the finger being designed tocushion the shock caused by the rapid movement of th armature 15 as itis rocked by the attraction of the magnet winding 12. It will beunderstood that the yielding action of the finger 90 is limited by theengagement of its lug 88 with the upper edge of the arm carried On'thearmature 15. The gripping member 55 is limited in its rocking movementby the engagement of its forwardly-extending finger 65 with the upperedge of the side wall 33 of the base 3|, and immediately this occurs thefinger 90 on the armature I5 will cause the gripping member 55 to slideforwardly along the base 3|. As the full force of the armature i5 isapplied by the finger 90 against the upright arm 51 of the grippingmember 55 to slide the slide 43 forwardly the detent 4| is released fromthe groove 49 in the side of the slide.

The forward movement of the slide 43 is limited to a distance equal tothe length of the ticket T to be applied as the shoulders 45 on the sideof the slide engage with the lugs 48 .at the end of the base 3|. As theslide 43 approaches this limit in its forward movement the finger 85 onthe gripping member 55 will ride down the inclined or beveled edge 66 onthe forward wall 33 of the base 3| to permit the gripping member to rockto a further extent in contraclockwise direction. This additionalrocking movement of the gripping member 55 causes the forward end of itshorizontal arm 56 to be forced downwardly across the cutting edge 5| onthe side of the slot 50 in the slide 413 to sever a length of thestrip 1. to form a ticket T which is held in extended position on theslide by the engagement of the resilient finger 6| therewith. Duringthis latter rocking movement of the gripping member 55 the spring 52therebeneath yields as indicated in Fig. 6 of the drawings. At thisstage in the operation of the ticket-applying means the end of thespring finger 6| will overlie the top of the severed ticket T and pressthe latter into the depression 63 at the end of the bottom wall of theslide 43.

The ticket T severed from the strip '6 is thus held momentarily inposition overlying the top of the bobbin b adjacent the base thereof asindicated in Figs. 3 and 6 of the drawings. At this juncture the end, ofthe strand y has been cause it to be carried around therewith andwithdrawn from the applying device 30. Nowpas the rotation of the bobbinb continues the strand of yarn 1 leading from the thread-guide ID willbe wound around the bobbin overlying the ticket 'I as indicated bydot-and-dash lines in Fig. 6 to securely fasten it in place by the coilsof winding in the bunch X. As the bunch X is completed the yarn y isreleased from the bunchbuilding means to allow the thread-guide It totraverse it to the full extent as indicated in Fig.

2 of the drawings to form the service windin on the bobbin b. The wholelength of the ticket '1 will thus be bound around the bobbin 2 exceptfor a slight portion at its end which is left projecting to display the'indicia thereon. The indicia may comprise one or more characters whichare duplicated at short intervals along the length of the strip t sothat at whatever point the strip is severed there will be at least oneset of characters showing as indicated in Figs. 2 and 9.

The cam 91 .which controls the operation of the ticket-applying means isso constituted and its operation ,so timed as to cause it to release theswitch 98 to open the circuit to the magnet winding I2 immediately theticket T has been delivered to the winding bobbin. Consequently, thedeenergization of the magnet winding '52 will effect release of thearmature 15 to cause it to be rocked in counterclockwise direction underthe action of the spring 78 to return it to itsinitial inoperativeposition shown in Fig. 5. During this rearward rocking motion of thearmature 15 the finger'86 carried thereby will engage the upright arm 57of the gripping member 55 to first rock the latter in clockwisedirection on the slide 34 and thereafter slide the slide rearwardlyuntil its ,end brings up against the wall 35 of the base 3! as thedetent 4| is engaged with the groove 49 in the side of the slide, seeFigs. 5 and 7. The rocking movement of the gripping member 55 in themanner last explained is limited 'by the engagement of the resilientfinger 6| with the lug 53 on the side wall 45 of the slide 43, see Fig.5. The initial rocking movement of the gripping member 55 raises its arm56 to release its end from the strip i so that it will pass over thestrip t as the slide 43 returns to its rearward position; the strip tbeing meanwhile held from retrogressive movement by the gripping actionof the two springs 31 and 38 with the forward end of the strip advancedslightly. beyond the end of the base 3|, see Fig. 5. Consequently, thestrip i will be fed forwardly again at the next operation of thegripping member 55 in the manner as previously explained. The machinewill continue to operate in the manner explained to arrest the rotationof the winding spindle upon completion of each bobbin B, doff the woundbobbin, don an empty bobbin b and attach the strand thereto, with thepresent device acting in timed sequence to deliver a ticket T inposition to be gripped to the bobbin by the winding of the strandthereon as the bunch winding is started.

It will be observed from the foregoing specification that the presentinvention provides a simple and compact device for automaticallydelivering tags, tickets or similar identifying ele--. ments andapplying them to the bobbins as they are wound in the machine. Thedevice is of such form and construction as to adapt it to be employed asan attachment for application to machines already in use by supplyingthe necessary electrical connections. The device is entirely automaticin its operation and reliable in per'-. forming its intended functionswhile being relatively inexpensive to manufacture.

While a preferred form of the device is herein illustrated anddescribed, it is to be understood 'that its mechanism may be modifiedand its application to use may be varied without departing from thespirit and scope of the invention. That is to say, the ticket-servingdevice may be arranged to apply the ticket to the bobbin in differentrelationship from thatherein shown, for

example by serving a gummed strip for attachment to the wooden base ofthe bobbin as the latter is gripped to the spindle-center or cup bywhich it is rotated. Therefore, without limiting ourselves to the exactarrangement and construction of the present device as herein shown anddescribed, we claim:
